DISINFEC'IING APPARATUS.

Specification of Letters Patent.

Patented Aug. 4, 1908.

Application filed April 8, 1908. Serial No. 425,872.

To all 21:71amit'may concern:

Be it known that I, YI'RGIL Annsrnoxo 'ILLIAus, a citizen of the United States, residing at Sedalia, in the county of Pcttis-and State of Missouri, have invented certain new and useful lm )rovements in Disinfecting Apparatus, of w iich the following is a specification.

The invention relates especially to securing uniform delivery of disinfecting liquid although the level of the liquid in a supplying reservoir varies materially.

It also relates to providing for replenishing such reservoir by merely pouring in additional fluid, and automatically controlling the discharge therefrom into an open con stant-level receptacle from which hquid esca es uniformly.

l igure 1 is a plan view of my device, the cover being removed. Fig. 2 is a section on the line 22 of Fig. 1.

A is an outer rece )tacle having a cover A and an outlet tube containing a wick B which extends downward to the bottom of the receptacle A. The upper portion of the vessel A and its cover A are )referably perforated as at A Centrally located within A is an interior reservoir C closed except as hereafter s ecitied. The reservoir C rests u on a brac'et or cup D in the lower iart oi the vessel A. For admitting liquid to the reservoir C there is a U-shaped tube E, having one branch extending up through the to of the reservoir and terminating in a funnel E. and having its other open branch terminating in the upper part of the reservoir at I. In the bottom of the reservoir C is a relatively small aperture F for permitting the [low of liquid into the supporting receptacle Alongside the reservoir C- a downwardly open tube G extends upward and 0 nuts into the upper part of the reservoir at The operation of my device is as follows, the parts being as embled as shown in the drawings:Liquid poured into the funnel l5 passes through the tube E and escapes at E 3 into the reservoir and as the opening F is relatively small, but a small portion of liquid 1 j means for pcrimttmg the gradual escape of will escape while the reservoir is being ill ed; air meanwhile esca )ing through G and G. When the level of I to liquid reaches G, the filling is continued until sullicient liquid has to establish equilibrium. As liquid 15 withdrawn from the vessel A by the capillary action of wick B, or by other devices, the liquid seal at G is broken, which automatically admits air above the liquid in C and allows liquid to llow out at F until G is again sealed and equilibrium reestablished.

My devices continue to operateuntil the liquid is exhausted, require no other attention than refilliin the reservoir when emptied. They involve no hermetic closure or valve for filling the aperture, nor inversion of any part in filling or refilling; they are certain m operation, have no moving parts to get out o order, and are filled without the attcndant putting his hands into the liquid or touching any parts in contact with the liquid.

I do not confine myself to the specific construction shown, as various obvious modifications may bemade without changing the invention. If desired, the bottom of the reservoir may be removable, allowing in spcction of the interior.

.Yha-t I claim is:

1. In apparatus of the class described, the combination with a liquid receptacle, of a. closed ll( uid reservoir communicating below with said receptacle and adapted to retain its contents by atmospheric pressure upon liquid in the latter, and a U-shaped tube extending ap )roximately to the bottom of the reservoir iaving one branch terminating in an open end within and at some distance above the bottom of the reservoir and its other open branch terminating at a higher )Olllt without said reservoir; whereby the iiquid in the reservoir may be replenished by pouring liquid into the upper end of said tube.

2. In apparatus of the class described, the combination with a liquid receptacle, of a closed liquid reservoir in said receptacle and rovided with an aperture for the escape of liquid and with a conduit, for the admission of air, terminating below approximately at the normal level of liquid in said receptacle,

liquid from said receptacle, and a U-shaped escaped through F and G'- to bring the level m the outer receptacle to G when the filling is stopped and the low l'rom G ceases.

tube extending approximately to the bottom of the reservoir and having one open branch terminating within and near the top of the reservoir and its other open branch termii nating at a. higher point without the re'ser However liquid will continue to escape from 1 voir.

F until the level in E falls to such a point as 2 s V s95,221'

In apparatus of the class described, the means for slowly removing liquid from the combination with a receptacle, of a closed receptacle, and a tube ha 'ing an open end in 25 reser oir communicating below through a v small a werture with said rece )t-acle an en conduit leading from a pointin the receptaele approximately at the height of the boti tom o: the reservoir into the upper portion or the latter. and means for permitting the gradual removal of liquid from said receptacle: whereby the lower end of said passage is at intervals uncovered by the liquid in the receptacle permit-ting air to enter the reservoir and cause the escape of liquid therefrom. to again seal said conduit.

4. In apparatus of the class described, the combination with an outer receptacle adapted to contain liquid, of a closed reservoir sup orted within and above the bottom of salt receptacle and provided with a, small aperture at its bottom, an open tube leading from a point, in the receptacle, approximately in the plane of the bottom of the reservoir, into the upper portion of the latter,

the upper part of the reservoir, extending i downward approximately to the bottom of the same, bending again upward, and terminating in an open funnel, above the plane of the end within the reservolr.

5. The combination with. an outer perforated receptacle having a removable cover, of a closed inner reservoir above the bottom of the receptacle and PIOVKlCd with a small aperture at'its bottom, an open tube leading YIRGIL ARMSTRONG WILLIAMS.
